Effect of Intercritical Annealing Conditions on Grain Growth Kinetics of Dual Phase Steel
Metals and Materials International - Tập 25 - Trang 1039-1046 - 2019
Fateme Najafkhani, Hamed Mirzadeh, Mehran Zamani
The study of grain coarsening and its kinetics during intercritical annealing is of vital importance for the production of dual phase (DP) steels with appropriate microstructure and properties required for industrial applications. In the present work, the kinetics of grain growth in the two-phase austenite plus ferrite region was studied based on the parabolic grain growth law. It was revealed tha...... hiện toàn bộ
Mechanism of corrosion fatigue cracking of automotive coil spring steel
Metals and Materials International - Tập 21 - Trang 1023-1030 - 2015
Tae-Heum Nam, Min-Seok Kwon, Jung-Gu Kim
The AISI 300M ultra-high strength steel was applied for the automotive suspension coil spring. Recently, some premature failures were reported, which caused by synergistic effect of cyclic mechanical stress and corrosion, namely corrosion fatigue cracking. In this study, the accurate mechanism of corrosion fatigue cracking for coil spring steel was studied for the proper prevention method against ...... hiện toàn bộ
Effects of rolling condition on the tensile properties of Mg-MM-Sn-Al-Zn alloy

Improvement of the decarburization rate in austenitic stainless steelmaking
Metals and Materials International - Tập 21 - Trang 118-125 - 2015
Youngjo Kang, Yong Hwan Kim, Ho-Sang Sohn
In order to enhance the decarburization rate at low carbon content region during the decarburization of molten stainless steel in argan oxygen decarburization, inert gas was blown into top slag and molten steel through a top lance. The carbon content at the end point of the decarburization process was found to reach lower values than conventional levels without the inert gas top blowing. The decar...... hiện toàn bộ
In-Situ Synthesis of Aluminum Matrix Composite from Al–NiO System by Mechanical Alloying
Metals and Materials International - Tập 27 - Trang 1631-1638 - 2019
Samaneh Mamnooni, Ehsan Borhani, Davoud Bovand
In this paper, Al-based composites reinforced by Alumina and Al–Ni intermetallic compounds have been successfully fabricated by mechanical alloying technique. The intermetallic phase, i.e., NiAl, NiAl3, Ni2Al3, as well as Alumina, were formed in the aluminum matrix by in situ solid-state reactions between pure Al and NiO powders. The effects of NiO content (7–10–13 vol%) on the characteristics of ...... hiện toàn bộ
Thermoelectric properties of the hot-pressed Bi2(Te0.85Se0.15)3 alloy with addition of BN powders
Metals and Materials International - Tập 6 - Trang 571-575 - 2000
Sun Kyung Lee, Jun Soo Lee, Dow-Bin Hyun, Tae Sung Oh
Thermoelectric properties of the hot-pressed Bi2(Te0.85Se0.15)3 alloy were investigated with the addition of BN powders as phonon scattering centers. The Seebeck coefficient and electrical resistivity of the alloy increased as the volume fraction of BN increased. Although the thermal conductivity of the alloy decreased as the volume fraction of BN increased due to the reduction of Kel, the lattice...... hiện toàn bộ
Influence of Ball Milling, Cold Rolling and Doping (Zr + 2Cr) on Microstructure, First Hydrogenation Properties and Anti-poisoning Ability of TiFe Alloy
Metals and Materials International - Tập 27 - Trang 1346-1357 - 2019
Peng Lv, Zhichen Liu, Abhishek Kumar Patel, Xingsheng Zhou, Jacques Huot
In this paper, we found that the first hydrogenation properties of TiFe alloy can be significantly improved by ball milling, cold rolling and doping. The samples by ball milling for 60 min and doped with (Zr + 2Cr) as additive showed a faster hydrogenation kinetics and the sample cold rolled for 5 passes showed the highest hydrogen capacity. Further study, it was clear that the first hydrogenation...... hiện toàn bộ
Load relaxation and creep behavior of a spray cast hypereutectic Al-25Si-2Cu-1Mg alloy
Metals and Materials International - Tập 16 - Trang 371-376 - 2010
Min Soo Kim, Young Won Chang
We studied the high temperature deformation behavior of a spray cast Al-25Si-2Cu-1Mg alloy within the framework of an internal variable theory for inelastic deformation. We then carried out a series of load relaxation tests at elevated temperatures to obtain flow curves between flow stress and strain rate. The results were analyzed based on constitutive relations prescribed by an internal variable...... hiện toàn bộ
